IMPROVEMENT IN CAR-TRUCKS.

Specification forming part of Letters Patent No. 208,058, datedSeptember 17, 1878; application filed g I October 26, 1877.

To all whom it may concern:

Be it known that I, AUSTIN BERRY, of Warden, in the Province of Quebecand Dominion of Canada, have invented certain new and usefulImprovements in Gar-Trucks; and

I do hereby-declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it pertains to make and use the same, reference being had to theaccompanying drawing, and to the letters of reference marked thereon,which form a part of this specification.

This invention has reference to oar-trucks mounted on wheels having adivided axle, and is designed to secure to the truck-frame a journal-boxof suitable construction for the abutting ends of the divided axle andto sus pend the swinging bolster from the truckframe by sprin gs locatedabove and below the truck, whereby equalizing-bars and the springsusually bearing thereon are dispensed with, the axles having no verticalmotion in relation to the truck-frame.

The invention'consists of a swinging bolster hung upon springs on thetop of the truckframe by means of hangers holding the sus-' pension barbelow, the latter bearing the springs on which the swinging bolster isplaced, whereby both sets of springs yield simultaneously to thepressure of the car, and in the combination and arrangement of theparts, as hereinafter more specifically set forth.

In the drawing referred to herein, Figure 1 is a side elevation of myimproved car-truck. Fig. 2 is a bottom view of the same. Fig. 3 is avertical longitudinal section. Fig. 4 is an end elevation, partly insection. Fig. 5 shows the journal-box detached. Fig. 6 shows the twoparts of the journal-box detached.

A designates the rectangular frame of the truck, provided with thecentral longitudinal bars B B, auxiliary bars B, and central trans versebars P for supporting the several parts of my construction.

0 indicates the divided or sectional axles of the wheels, the abuttingends bearing in a journal-box, D, attached firmly to the under side ofthe bars B by stirrups o c and braces (Z (I, bolted to the intermediatebars of the frame A, as shown,or by othersuitable means.

The outer journals of the axles have bearin g in boxes having novertical sliding motion in the jaws E, secured to the truck A in theusual manner, and the usual equalizing-bars and springs thereon aredispensed with. The abutting ends of each axle are formed with ajournal,F, and collar Gr, and a bushing, H, in the upper section of thebox 1) has a groove therein to receive the collar, so that when thewhole is secured the sections of the axle have no endwise pressure onthe jaws E to strain them out of place.

The boxes D are formed of upper and lower sections, rigidly securedtogether and to the bars B by the stirrups a, passing through the braces(Z d, and having nuts I on their ends, and to prevent the stirrups wherethey pass over the bar B from sinking therein saddles T are interposed.

The lower section of each of the boxes D is formed with apacking-chamber, J, which is "fed with oil from a reservoir, V, abovethe bearing through a connecting-tube, K. The

lubrication of the outer journalsof the axle is effected in the ordinaryway and by the usual means. 7

The car rests on the usual center casting,

which is in position mid-length of the swinging bolster L, resting onthe upper parts of elliptic springs M M, which are secured upon thesuspension-bar N, suspended by hangers O, sliding loosely through thetransverse timbers P of the truck-frame. The hangers O are provided withheads S, bearing on springs Q, seated on washers It, bearing on the topof the timbers P, the hangers passing through them and securingbearing-plates W near both ends of the bolster, and supporting the sameby nuts to on the lower ends of the hangers.

The swinging bar is thus provided with springs above and below thetruck, and the springs will yield correspondingly to the weight of thecar. The axles, having no yieldin g motion, will cause the truck tocarry more than an ordinaryload and be run with greater safety, theweight of the load being distributed from the outer ends of the axlestoward the center.

I claim as my invention- 1. The combination of the saddles '1, centralbar B, and stirrups (3, substantially as shown, and for the purposedescribed.

2. The combination of the swinging bolster L, elliptic springs M,suspension-bar N, hangers O, with heads S, springs Q, with washers R,and bearingplates W, with nuts u, substantially as shown and described.

3. The boxes D, secured to central bars B of the truck by stirrups 0,provided with saddles T, and by braces d bolted to the frame A, andsecured to the stirrups by nuts I, all in combination, as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
